l e known that I, Renown Rarsaxrren, a n of the Unit-ed States, residing at St. in the county of Buchanan and State uri, have invented certain new and Improvements in Motors for Washingifirr lifs. &e., of which the following is a.

.cation.

P 1 Eng machines 630.; and my objects are to de a machine of this character which have ample. power to properly perform :11, which is simple in construction so -t will not require the attention of a mat mechanic, and one that may be produced a! comparatively small cost.

in order that the invention may be fully understood, reference will now be made to theaccompanying drawings, in which:

Figure 1 represents an elevation, partly in section of the machine. Figs. 2 and 3 are cross sections of the motor taken on lines II and ill, respectively, of Fig. 5. Fig. -i is a broken plan view of an agitator and its drive shaft, the latter being in cross section on line 1V-IV of Fig. Fig. 5 is an en larger! vertical section of the motor and the agitator on line V-V of Fig. 6. Fig. 6 is a horizontal section on line VIVI of Fig 5.

For convenience in illu ting the inven tion I have shown it applied to a, wash-tub 1, whieh normally closed by a lid 2.

3 designates an agitator for stirring the clothes and agitating the water so that it will he forced through the clothes and thus thornv hl cleanse the same. Said agitator is adj-.zsta )ly mounted upon a vertical drive shaft 4, so that it may slide up or down thereon, and thus aewmmodate itself to the quantity of clothes within the. tub. Said agitator is provided with an eleneated socket '3. having OI)pflfiitei:f(liSpOS(iT reces es 5 for the reception of a pair of hugs T at the lower end of the drive shaft. This arrangement permits the agitator to slide up or down upon the shaft and yetbe rotated there-n5: The downward movement of the agitator is limited bv a set-screw S in theupper end of the s cket, which is adapted to engage one of the lugs 7.

Socket. 5 is providcd with a plurality of threaded openings 9 arranged at. Various heigi' s 1" )T the reception of the set-screw, so

that the vertical adjustment of the "qitator Specification of Letters Patent.

his invention relates to a motor for wash- 4 of Yokes i may regulated as desired. For tnfiance, i if the tub is shallow the set:serew is placed l Patented Aug. 4,- 1908.

in one of the lower openings to shorten the downward movement of the agitator, and when the tub is deep the agitator .5 permittcd to drop further down by placing the seto screw in an upper onening.

Shaft 4 is ournaled at its up'er portion in ball-bearings 10 arranged in a musing 11. 12 designates a pinion detachably secured te the drive shaft by apin 13, so that said shaft may be removed from its hearing when desired by withd "awing said pin. Pinion l2 isrotated in reverse directions by a reciproeatery. rack-bar 14, extending through the housing and held in engagement with iinion 12 by: an nntifrietion roller 15, journa ed in the housing.

Raclt bar 14 is removably secured at one end to a iistion-head 16 forming part of a reciprocatoi motor, whereby the machine is operated. iaid motor is driven by iluid pressure, water being preferably employed on account of the coiu'enienee with which the motor may be connected toa faucet. In eonstrm'ting said. motor I employ a centrall \'-disposed cylinder-head 17 to which a pair of oppositely-dis vposed cylinders l8 19 are removahly seeured,"said cylinders being open at their outer ends and closed at their adjacent ends by head 17. "Head 17 is pro vidcd with o i .ositely-disposcd inlet and exhaust ports 20 31, having externally thread ed walls 22 23, res n-.ctively, of proper size to receive standard couplings so that inlet '20 may be connected by hose (not shownlto :1 faucet, and the exhaustconnected by a hose (not shown) for the purpose ofconducting the used iluid to the in point.

inlet 20 conuuunicates with a chamber .24 which in turn communicates with two oppositelywlisposed channels 25 26, extending through head 17 and communicating with cylinders 18 19, respectively. Fxhaust port, 21 communicates with a chamber 27 also arranged within head 17 and communicating with e linders l8 1!) by two 0 )positely-dis posed channels 2% 2!) respectively. (onnnunieation between chamber 2-! and channels 25 :26 is 'altern.-itel controlled by an inletvalve 30 extending thcrethrongh, said inlet valve being provided with a centrally-disposed disk 31 and.a pair of oppositely-dis posed stems 32 33, extending through a pair t 35. provided with a pair of centrally-disposed butters 36 37, respectiv ly, '-l'he How of water through channels 2 29 or other desired is controlled by an exhaust valve 38 extending thercthrough and provided near its opposite ends with a pair of disks 39 40 for arterheaded ends of stems 32 33.

45 46 designate a pair of expansion springs interposed between the ends of valve 38 and yokes 34 35, for the pur ose of normally "holding the same against t e headed ends of stems 4'1 42.

47 designates a piston-rod, one end of which carries the piston-head 15, while its opposite end carries a duplicate piston-head 48, reciprocably arranged in cylinders 18 19,

respectlvely. The piston-rod -17 is provided at;1ts op ositesides with stufiing-boxes 49 to prevent eakage of the motive fluid from one cylinder to the other.

The motor is supported by a pair of feet 50 and a frame 51, to which latter the former is secured by screws and retaining-nuts 52 53, respeetivel Frame 51 is relnovably secured to lid 2 in any suitable manner and has a duct 5; extending beneath the entire length of the nlotor, and communicating at its discharge end 55 w-ith the interior of the tub, so

that should the motor leak, the fluid therefrom will be conducted to the' tub.

When the motor is not in use durin cold weather I drain the-fluid therefrom so t at it will not freeze therein, through a passageway 56 leading from cylinders 18 19 and comnumicating with an outlet 57 controlled by a valve 58.

channels :25 2?, respectively. The closing of channel 25 will cause the fluid to enter cylinder 19 through channel 26, and force piston-head 48 to theend of its outward stroke, see Figs. 5 and 6. This movement of pistonhead 48 will carry the piston-head 16 to the right until it contacts with buffer 36 and, through the instrumentality of the intervening parts, move'valvcs 30 and 38 to the left and cause them to open up communication between chambers 24 27 and channels 25 28, respectively. moves to the right as above described, it will force the fluid from c linder 18 through channel 28, through whic 1 it flows to chamber 27, and thence out through the exhaust ort 21.

From the above descri tion it wil be un-' de'rstood, that the cyliru crs are alternately charged with a fresh supply of motive fluid,

while the used fluid is being alternately discharged from said cylinders. The reciprocatory motion of the piston will be communicated to the rack-bar 14, which will, through the instrumentality of the intervening parts rotate the agitator first in one direction and then the other.

Having thus described my invention, what 1. A motor of the type set forth embodying a frame formed with a longitudinal inclined duct on its .top face and with a vertical discharge passage at one end communi catin with the lowest cmt of said duct, 3. cylinder head, feet carried by said head scoured to central points alon the length of said frame on o posite sides of said duct, cylinders carried iiy said head, pistons in said cylinders and inlet and exhaust valves for said pistons, a iston rod connected to said pistons, a rack ar connected to the piston,

an operating shaft passed through said dis charge passage of sald frame, and a pinion on said shaft in mesh with said rack.

2. A. motor embodying a frame having a, longitudinal duct therein, a c linder head secured to said frame and over yin said duct,

When the piston-head 16' cylinders on opposite sides of said head, connected pistons in said cylinders, inlet and exhaust valves for said pistons, and means to drainthe water from each of said cylinders consistirn of a passage-way extending through said cylinder head so as to communicate with each of the cylinders, and an outlet formed in said cylinder head at an intermediate point so as to communicate with said duct, and a valve for the outlet threaded in one of the walls of said 0 linder head.

In testimony whereof I a 1): my signature,
